Cost & Project Planning Hub
Construction costs depend on size, specification, structural complexity, and site conditions. This hub consolidates budgeting principles, quotation reviews, and estimator guidance to help you plan your project accurately.
Budgeting Principles
The primary drivers of project cost include the existing condition of the property, structural alterations, layout changes, and the specification level of finishes (e.g., standard vs. premium).
A generic per-square-metre rate cannot replace a site-specific assessment. Hidden defects, ground conditions, access restrictions, and party wall requirements all significantly influence the final cost.
Quotation Inclusions & Exclusions
A useful written quotation sets out the agreed scope and should distinguish between what is supplied and fitted versus fitted only.
When comparing quotes, evaluate the assumptions and exclusions. Determine how client-requested variations or unforeseen additional works are managed before proceeding.
Comparing Quotes
It's essential to compare scope, not just headline figures. If one quote is dramatically lower, it may exclude necessary preparation work, structural elements, or building control coordination.
Review the contractor's references, insurance, assumptions and whether coordination with appointed professionals is included. The most useful comparison is the documented scope, not simply the lowest or highest headline figure.
Risks & Contingencies
Opening up existing structures can reveal unforeseen conditions. Maintain a contingency budget to handle unexpected requirements like upgraded drainage or additional structural support.
Clear communication and a documented variation process are key. Understand how your contractor handles changes and secures written approval before undertaking additional work.
